7 Claims.

My invention pertains in general to packaging apparatus and specificallyrelates to a construction of universal wrapping machine.

One of the objects of my invention consists in providing a universalwrapping machine capable of producing conditioned sheets of packagingmaterial for wrapping and packaging purposes.

Another object of my invention comprises providing a construction ofwrapping machine for selectively utilizing difierent components invarious relationships for providing packaging material for wrappingpurposes.

A still further object resides in the provision of a wrapping machineconstruction having a special form of material supply means and severingmeans together with an optional gluing arrangement for permitting theeflicient and rapid pro vision of sheets of packaging material,particularly coated regenerated cellulose, for wrapping operations.

.These and other objects will be apparent from the following, referencebeing made to the accompanying drawings which form a part of thisspecification and in which like reference numerals designatecorresponding parts throughout.

In the drawings:

Fig. 9 is a side view of the representation of Fig. 8.

Referring to 'the drawings in .detail and particularly to Figs. 1 and 2,there are provided a pair of side supporting elements I and 2 secured inseparated position by transverse rod members 3, 4 and 5. The rod members3 and 5 are provided at their opposed ends with cushioning members 6 andl which may be formed of rubber or other suitable material. Upon theinner sides of members and 2 there are provided a plurality of mountingreceptacles l and II, l2 and I3, in which transverse rods l4 and I areremovably positioned as may be seen from Fig. 1. Upon the rods l4 and I5rolls of packaging material I! and I3 may be mounted as desired. Thismaterial is preferably of coated transparent regenerated 1935, SerialNo. 11,756

and I8 are brought down respectively under transverse members 23 and 24,extending between the supporting members and 2. Under member-'23 the twoends 8 and I6 of the ribbon-like packaging material are superimposed andfed around transverse rods 29 and 30 and thence around rod 3| and overthe cutting platen 32. (See Fig.2.)

Referring to Fig. 1, a rod 34 is mounted above the rod 3| and may beprovided, if desired, with gluing units. The construction of one ofthese gluing units will be apparent from Figs. 1 and 2 in which it willbe seen that hook members 35 and 36 depend from the rod 34 and supportthe glue-containing receptacle 31. Between the hook members 35 and 36 asleeve 38 is mounted on the rod 34 and provided with a set screw 386 forposi tioning the gluing unit in any desired spatial relationshiptransversely of the machine for effecting a gluing operation on thepackaging material fed around the rod 3|. Internally of the gluecontainer 31 is a wheel 4|! which dips into the glue in the container 31and applies the same in a restricted line to the material as it passesaround the rod 3|. The weight of the gluing unit holds the wheel 40against the material on rod 3|, and the linear movement of the materialcauses the rotation of the gluing wheel 40. A scraper lid 42 covers thegluing unit and is provided with a slot through which the disc 40 mayrotate against the material. This lid may be adjusted backand forth todetermine the amount of glue adhering to the wheel 40. This adjustmentis effected by means of screw assembly 43 as shown in Fig. 2. Anothergluing unit 42:: is shown mounted upon the rod 34 and is of aconstruction similar to the previously described gluing unit. Inaccordance with the construction of my invention, these gluing units maybe inserted or removed at will and especially positioned for anyparticular form of gluing operation, as desired.

Above the platen 32 a pair of transverse guide rods 45 and 46 aremounted between the upright members and 2. Mounted for movement on theseguide rods there is provided a cutting unit which, in accordance withthe present invention, may be of different forms. In the first form ofthis cutting unit, there is provided a mounting member 41 which includesa bearing sliding upon the guide rod 45. This mounting member 41 alsoincludes a housing supporting a rotatably mounted cutting wheel 48. Thebearing portion of mounting member 41 has a free rotative movement uponthe guide rod 45 to bring the cutting wheel '48 into cuttingrelationship with the platen 32 under pressure. The wheel 48 has acutting edge as will be apparent from an inspection of Fig. 2. A handlemember 49 is connected by a pressure spring 50 with the mounting member41, and is carried by the yoke 41a mounted as a swivel on rod 45.

A ball-bearing unit Si is rotatably mounted in the handle structure asshown and is provided with a concave periphery which engages the guiderod 46. In efiecting a cutting operation, the operator grasps the upperportion of the handle structure 49 and exerts a downward pressurethrough spring 50 to cause the cutting wheel 48 to sever the packagingmaterial on the platen 32 while imparting a transverse sweep to thecutting unit as a whole to traverse the material. A transverse materialpositioning member 39 is constructed in a mechanically complementaryfashion with respect to a recess provided longitudinally along theplaten 32. This member 39 is mounted in slots at either end of theplaten for permitting a slight vertical movement whereby the weight ofthe member normally depresses the packaging material within the recessof the platen 32. Before a cutting operation is consummated, the weightof this element causes the extending portion of the ribbon-likepackaging material to assume an upright position extending away from theplaten 32 so that the operator can grasp this portion of the materialand pull it out to a desired length. Thus the operator may use one handfor feeding the material and the other hand for effecting the cuttingoperation as desired. In connection with the cutting operation, a board55 is hingedly secured to the rod 3 as shown and may be provided withcutting indicia or a scale for effecting the cutting of proper lengthsof the packaging material.

The cutting unit used in the invention is provided with gluing unitsas'may be seen in Fig. 5. These gluing units consist of funnel-shapedglue containers 51a and 5117, having feeding pipes 584 and 58b extendingdown adjacent the cutting wheel 48 proximate to the material to be cut.A wire 59 extends into the opening of the pipes 58a and band isconnected, in each instance with pivoted elements Glu and Gib controlledin their movement by the manual pressure on the handle member 49 wherebythe flow of glue to the packagingmaterialisaccordinglyadiusted.Asiurther shown in Fig. 1, the pair of glue units 51a and 51b areprovided with their flow pipes 580 and 58b extending upon opposite sides01' the cutting wheel 48 for applying a thin strip of glue to thepackaging material upon both sides of the severing line. Althoughcertain specific forms of gluing arrangemen-ts have been shown it isrecognized that various modifications and changes can be made toaccommodate and meet the requirements of various conditions. Forexample, the apparatus of my invention may, when desired, dispense withthe gluing arrangements associated with the handle 49, as shown in therepresentations of Figs. 3 and 4. I

A further use and arrangement of the foregoing apparatus may be observedin Figs. 3 and 4 in which the roll of material I! has been removed andin place thereof a moisture-applying roller 65 has been provided. Amoistening pan 88 is 88. A spindle removably mounted beneath the rollerGS upon positioning pin 81 and may be provided with water or other fluidfor moistening theperiphery of roller 85. In this arrangement the ribbonfeeder extending from the roll of material I8 is brought up from rod 24around the roller 28 and under the rod 23 and thence around the otherrods 29, 38 and 3| to the platen 32. Under such conditions, thecellulose packaging material is moistened as the material is fed to theplaten 32. The spacing between rods 23 and 3| permits partial drying ofthe material before reaching the platen 32 so as to have a desiredmoisture treatment. Such an arrangement is particularly advantageouswhen it is desired to apply cellulose material to packages by theshrinkage process such as in the wrapping of bottles and the like.

Another form of the cutting unit can be seen in Figs. 6 and 7. Referringto these figures, a unitary mounting structure 18 is provided andincludes a yoke having legs H and 12 provided with sliding bearingsmounted on the guide rod 45. The upright portion of the mountingstructure 18 terminates in a handle portion 15. Ex-

tending through this upright portion of the structure l8, and above theyoke member's II and 12, there is threaded a stud 18 having a slottedend accessible for adjustment from the front of the machine. The otherend of the stud is provided witha concave bearing member 11 which may becomposed of fiber or other suitable material. The member 11 engages therod 48 under adjustment of the stud 18. A lock nut 18 is provided forsecuring the stud 18 in an adjusted position. In this arrangement, acutting strip is removably mounted upon the upper surface of the platen32 and is secured thereto by screws 8|. 80 is of rectilinearconstruction and is preferably composed of hardened steel or a similarmaterial. A cutting wheel 82 is rotatably mounted upon a spindle 83extending from the front of the mounting structure 10 as shown in Fig.7. The cutting wheel 82 is of somewhat difierent'constructlon than thepreviously described cutting wheel 48, inasmuchas the cutting wheel 82has a flat periphery engaging with platen 32 and a side,-at right anglesto the periphery, engaging the strip 83 is provided with a screw head 84for permitting removal or adjustment with respect to the structure 10. Aspring 85 is mounted upon the spindle 83 between the head 84 and a hubof the wheel 82 for exerting pressure toward the structure 18. As willbeseen in Fig. 7, the material is normally held, by weight of the member39, in a distendedposition, as represented by the dotted line, forenabling the operator to easily grasp the same and pull out the properlength. When the proper length has been pulled out, the handle 15 may begrasped and a transverse sweep imparted to the cutting unit whereby thecooperation of cutting wheel 82 and strip 80 produces a shearing efl'ectwhich severs the material. An especial advantage of such a shearingoperation is that the cutting elements employed are given to long lifeand at the same time offer no sharp edge which might be dangerous tounskilled operators. It will be noted that in both cutting operationsherelnbefore described, a cutting operation can be effected in bothdirections across the machine. Either one of the arrangements of cuttingunit described and depicted may be employed as' desired in the variousembodiments of my invention.

Figs. 8 and 9 represent a treadle-operated form of the invention. Inthis arrangement. the cut- The strip ting machine is mounted upon astructure having upright leg members 90. In this instance either form ofthe cutting unit may be used for treadle operation, thereby enabling theoperator to have 5 both hands free for wrapping and other manipulationsof the packaging material aside from cutting. The cutting unit isprovided with a flexible cable 92 which extends through holes in theupright members I and 2 to pulley units 93 and 94 rotatably mounted uponopposite sides of the machine as shown in Fig. 8. After passing overthese pulley units the cable 92 then extends around pulley units 95 and96. In the lower part of the structure and between a pair of the legs90, two treadles 91 and 98 are mounted for independent foot operation.The treadle 91 is connected by a coupling unit 99 with the cable 92 at apoint between the pulley units 93 and 95, while treadle 98 ismechanically connected by coupling unit I00 to the cable 92 at apointbetween the pulley units 94 and 96. Thus the operator, positionedin front of the machine, can utilize his feet to independently impart atransverse cutting motion to the cutting unit respectively in oppositedirections while having his hands available for other purposes inconnection with the packaging operation.

The wrapping machine of my invention is universal in its aspects and hasvarious uses which, 30 from the foregoing description and disclosure,

will be apparent to those skilled in the art. Various combinations andarrangements for wrapping articles can be effected. For example, pluralsheets of cellulose material of the same or different characteristicscan be superimposed in varying spatial relationships for wrappingarticles or forming packages. In another aspect of the .same machine,moistened material can be utilized for packaging by the shrinkageprocess. 40 These and other uses of the invention may suggestmodifications to those skilled in the art but which will not depart fromthe intended scope of my invention. I do not therefore desire to limitmyself to the foregoing except as may be 45 pointed out in the appendedclaims.
